I've installed UnixUtils that's why I can run this kind of commands on windows.
It's executed when browsing a PHP file(http://localhost/filename.php) on windows.
The web server is Apache.
I think it should be divided into 2 steps:
1.found user of Apache threads
2.give enough permissions to that user towards "F:/tmpJob/"
I checked httpd.conf and found:
User daemon Group daemon
But there is no "daemon" user on windows. How to find the real user of apache threads?
